Objective To compare the efficacies of early intensive and moderate insulin therapy on the prognosis of patients with severe acute pancreatitis (SAP).Methods The clinical data of 78 patients with SAP complicated by hyperglycemia who were admitted to the Second Hospital of Lanzhou University from January 2005 to December 2009 were retrospectively analyzed.All patients were divided into the intensive insulin therapy (IIT)group (31 patients) and moderate insulin therapy (MIT) group (47 patients).The target levels of blood glucose were 0.80-1.10 g/L(4.4-6.1 mmol/L) in the IIT group and 1.44-1.80 g/L(8.0-10.0 mmol/L) in the MIT group,respectively.The effects of the 2 therapies on the prognosis of the patients were compared.All data were analyzed by the t test or chi-square test.Results The daily intravenous insulin dosage,fasting glucose level and incidence of severe hypoglycemia were ( 35 ± 11 ) u,( 1.02 ± 0.13 ) g/L[ (5.7 ± 0.7 ) mmol/L] and 10％ (3/31 )in the IIT group,and ( 24 ± 15 ) u,( 1.58 ± 0.21 ) g/L[ ( 8.8 ± 1.2 ) mmol/L] and 2％ ( 1/47 ) in the MIT group.A significant difference was detected in the daily intravenous insulin dosage between the 2 groups( t =12.76,P ＜=0.05),but no significant difference was detected in the incidence of severe hypoglycemia between the 2 groups (x2 =0.91,P ＞ 0.05 ).The levels of albumin and prealbumin on the 14th day were ( 34 ± 6) g/L and (231 ± 31 ) mg/L in the IIT group,and (35 ± 5)g/L and (241 ± 29)mg/L in the MIT group,respectively,with no significant difference between the 2 groups( t =-1.94,-1.68,P ＞ 0.05).The incidences of abdominal infection,circulatory dysfunction,respiratory dysfunction and acquired kidney injury were 23％ (7/31),32％ (10/31),26％ (8/31)and 13％ (4/31) in the lIT group,and 26％ (12/47),36％ ( 17/47),30％ (14/47) and 23％ (11/47) in the MIT group,with no significant difference between the 2 groups(x2 =0.09,0.13,0.15,1.33,P ＞ 0.05).The scores of APPACHE Ⅱ on the 14th day were 9 ± 4 in the IIT group and 9 ± 3 in the MIT group,respectively,with no significant difference between the 2 groups ( t =- 0.60,P ＞ 0.05 ).There were 4 ( 13％ ) patients in the IIT group and 7( 15％ ) patients in the MIT group died of multi-organ dysfunction syndrome,including 2 patients in the IIT group and 6 patients in the MIT group complicated with sepsis.There was no significant difference in the mortality between the 2 groups ( x2 =0,P ＞ 0.05 ).Conclusions Compared with MIT,early IIT could not improve the prognosis of the patients with SAP.MIT is appropriate for SAP patients complicated with hyperglycemia.

With the deepening research of comprehensive treatment for gastric cancer, the FLOT regimen has begun to be used for the treatment of gastric cancer patients. FLOT neoadjuvant regimen can significantly improve the R 0 resection rate and prolong the overall survival time of locally advanced gastric cancer patients. FLOT regimen combined with immune-checkpoint inhibi-tors, targeted therapy and hyperthermic intraperitoneal chemotherapy have great potential in neo-adjuvant therapy for gastric cancer. The authors systematically analyse the development history and latest clinical research progress of FLOT neoadjuvant regimen for gastric cancer based on their clinical practice experience.

OBJECTIVE: To determine the clinical value of laparoscopic cystogastrostomy in the treatment of pancreatic pseudocyst. METHODS: Twenty-one patients with pancreatic pseudocyst received total laparoscopic cystogastrostomy. The data on intra-operative bleeding, operative time, post-operative time to get out of bed, time of first flatus/bowel motion, complication and duration of hospital stay were observed and analyzed retrospective1y. RESULTS: Twenty-one patients were successfully carried out the laparoscopic surgery. The average operation time was 90(62-120) min. The blood loss was less than 100 mL in all patients. The average time of hospital stay was 8 d. After 12-18 month follow-up, all patients recovered smoothly without any complication. CONCLUSION Total laparoscopic cystogastrostomy with the posterior approach is a feasible, safe and minimal invasive procedure for pancreatic pseudocyst, which can be recommended to the clinical application.

Gastric cancer (GC) is one of the most common malignant tumors with high heterogeneity. According to Lauren classification, GC is divided into intestinal type and diffuse type. With rapid progress in technologies and ideas in the clinical diagnosis for GC, the normalized and individualized comprehensive treatment has become the main trend. However, the clinicopathological characteristics, remedy and prognosis for GC may be different because of the different classifications and stages.

OBJECTIVE: To explore the prognosis and surgical method for diffuse-type advanced gastric cancer (AGC).
 METHODS: The clinicopathological data of patient, who underwent curative gastrectomy in the Second Hospital Affiliated to Lanzhou University from 2005 to 2010, were analyzed retrospectively. The prognostic factors of diffuse-type AGC were analyzed by Cox regression models. The patients were divided into a total gastrectomy group (n=120) and a subtotal gastrectomy group (n=167) according to the surgical approach. Survival rates were established by the Kaplan-Meier method and compared by the Log-rank test between the total gastrectomy group and the subtotal gastrectomy group.
 RESULTS: A total of 287 patients with diffuse-type AGC were enrolled in this study, including 120 patients in the total gastrectomy group and 167 patients in the subtotal gastrectomy group. Univariate analysis showed that the prognosis of diffuse-type AGC was associated with body mass index, number of retrieved lymph nodes, Borrmann type, tumor size, T stage, N stage, tumor-node-metastasis (TNM) stage, extent of resection, surgical margin, postoperative complication, perineural and vascular invasion (all P<0.01). Multivariate analysis showed that normal body mass index, tumor size, T stage, N stage, total gastrectomy, surgical margin, postoperative complication were the independent predictors for diffuse-type AGC (all P<0.05). The 5-year overall survival rate and progression-free survival rate for diffuse-type AGC after curative gastrectomy were 17.8% and 13.6%, respectively. The median survival time and progression-free survival of them were 22 and 18 months, respectively. The overall survival rate and progression-free survival rate in the total gastrectomy group was significantly higher than that in the subtotal gastrectomy (P<0.01); the extended extent of lymph node dissection, the lower rate of positive surgical margin and postoperative complications were present in the total gastrectomy group (all P<0.05 or P<0.01).
 CONCLUSION The patients with diffuse-type AGC have a poor prognosis. The great tumor diameter, advanced T stage, advanced N stage, subtotal gastrectomy, high rate of positive surgical margin and postoperative complication are independent risky factors for the diffuse-type AGC. However, the total gastrectomy may be beneficial to patients.
